Answer 1

$a) \: \sqrt{64 \div 16} = \sqrt{4} = 2$

$b) \: \sqrt{( - 5) {}^{2} } = \sqrt{25} = -5$

$c) \: \sqrt{121} = 11$

$d) \: \sqrt{ {5}^{3} \times 5 } = \sqrt{ {5}^{4} } = {5}^{ \frac{4}{2} } = {5}^{2} = 25$

$e) \: \sqrt{ {32}^{3} } \div \sqrt{ {2}^{3} } = \sqrt{ \frac{ {32}^{3} }{ {2}^{3} } } = \sqrt{ \frac{ ({2}^{5}) {}^{3} }{ {2}^{3} } } = \sqrt{ \frac{ {2}^{15} }{ {2}^{3} } } = \sqrt{ {2}^{12} } = {2}^{6} = 64$
